TVS - Varistors, MOVs

Varistors or metal oxide varistors, present in most surge protection devices, are non-linear resistive components, successfully employed in wide range applications such as lightning and transient overvoltage protection. Varistors perform an essential lead role in the performance and dependability of the majority of the surge protectors used in the electronics industry.

Metal oxide varistors or MOVs, or metal oxide varistors, are widely used in the electronics industry due to their solid-state, preassembled, ready-to-integrate components with necessary surge protection capability present in the component itself. MOVs are voltage dependent resistors (VDRs) that have metallic oats and oxide cores pressurized together to create a stable non-linear resistance.

The capacitance of a MOV also plays an important role in the surge protection performance. From the capacitance characteristics, one can observe that the capacitance value increases with the voltage, meaning that the MOV works as a capacitor, providing a path to the ground for short-term surges.

The 0072.4661.B1 Varistor is a MOV designed for reliable use in the protection of different industrial environments. The metal oxide core used in the 0072.4661.B1 Varistors offers up to 20KV surge protection and is rated for 1KV continuous AC working voltages.

The component is packaged in a cylindrical case with two terminals that can be connected to the electrical circuit in which the device is installed. In addition, the component has been built to withstand hostile environmental conditions, such as high temperatures, humidity and shock.

The working principle of the 0072.4661.B1 is similar to other MOVs. Its nonlinear resistive behavior means that, when a voltage that exceeds its allow operating range is applied across the device, the current flowing through it will be limited, providing protection to the system connected to it. When the overvoltage is removed, the MOV will return to its normal resistance level.

In addition, the component has a capacitive property which provides it with additional surge protection properties. As the voltage applied across the MOV increases, the capacitance of the component increases, allowing it to act as a capacitor and provide an additional path to the ground for the surge current.

The 0072.4661.B1 Varistor is designed for use in many different industrial applications, such as electronic equipment, mechanical and electrical control systems, medical equipment, telecommunication, power supplies and more. The device can be used in many different environmental conditions, and is often found in outdoor locations where the protection requirements are high.

The 0072.4661.B1 Varistor is an essential component used in surge protection devices that offer reliable protection in a wide range of environments. Its performance and dependability make it the ideal choice for industrial surge protection applications. This component is designed for reliable use and provides users with the necessary surge protection capability.
